When the electronic strength tester is used, the force measuring device of the electronic strength tester is required. Although there are many types and quantities of force measuring devices of current electronic fabric strength machines, there are still certain problems in the existing force measuring devices of electronic fabric strength machines, which brings certain inconvenience to the use of force measuring devices of electronic fabric strength machines. A Chinese patent discloses a force measuring device of an electronic fabric strength machine (authorization announcement number CN216433740U). The patent technology can fix the fabric through a clamp, and then drive the winding roller to rotate by a motor, so that the winding roller drives the lifting plate to move upward through a pull rope, stretch the fabric through the clamp, monitor the tension through a sensor, and replace the double screw drive with the winding roller and the pull rope to avoid the clamp from being stuck during lifting and lowering, so that the clamp can be lifted and lowered smoothly. However, when the above-mentioned clamp clamps the fabric, because the fabric itself is relatively smooth and soft, and is easy to deform, the fabric is easy to fall off from the clamping clamp when subjected to a large tension, thereby failing to complete the detection of the fabric strength. Therefore, a force measuring device of an electronic fabric strength machine is provided to solve the problems raised in the above-mentioned background technology. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] See also Figures 1 to 4 A force measuring device for an electronic fabric strength machine comprises a base plate 1, a sliding groove 2 is provided on the base plate 1, a servo motor 201 is installed inside the sliding groove 2, a threaded screw 202 is fixedly connected to the output end of the servo motor 201, a first clamping assembly 203 is arranged on the threaded screw 202, a fixing frame 4 is fixedly connected to one side of the base plate 1, a sliding groove 401 is provided on the fixing frame 4, a second clamping assembly 3 is slidably connected inside the sliding groove 401.

[0021] Among them, the first clamping component 203 can be moved left and right on the base plate 1 through the threaded screw 202, wherein the tension direction of the second clamping component 3 is fixed, and the position of the first clamping component 203 can be changed, so that the state produced when the fabric is subjected to tension at different angles can be detected.

[0022] Specifically, the first clamping assembly 203 includes a clamping frame 204, which is internally slidably connected to a clamping plate 205, to which a spiral rod 206 is spirally connected, which is rotatably connected to the clamping plate 205, a protrusion 207 is fixedly connected to one side of the clamping plate 205, and a groove 209 is provided on the side of the clamping frame 204 adjacent to the clamping plate 205.

[0023] The first clamping assembly 203 and the second clamping assembly 3 have the same structure. By arranging the same first clamping assembly 203 and the second clamping assembly 3, the fabric can be stably clamped and the fabric is not likely to fall off.

[0024] Preferably, a plurality of ejector pins 208 are fixedly connected to the protrusion 207 , and a plurality of pinholes 210 are formed inside the groove 209 .

[0025] The fabric itself has a plurality of gap holes, and when the protrusion 207 presses the fabric tightly inside the groove 209, the ejector pin 208 will penetrate through the gap holes on the fabric into the needle hole 210, thereby fixing the position of the fabric inside the first clamping component 203 and the second clamping component 3, so that the fabric is not easy to fall off.

[0026] Preferably, a servo motor 404 is installed on the fixed frame 4, a winding roller 405 is installed on the output end of the servo motor 404, a suspension rope 402 is wound around the winding roller 405, a tension sensor 403 is fixedly connected to the lower side of the suspension rope 402, and the tension sensor 403 is installed on the clamping frame 204 of the second clamping assembly 3.

[0027] Among them, a PLC is set on one side of the base plate 1, and the PLC is electrically connected to the servo motor 201, the servo motor 404 and the tension sensor 403. When the servo motor 404 drives the winding roller 405 to rotate, the suspension rope 402 will be wound around the winding roller 405, so that the second clamping component 3 is driven to slide inside the slide groove 401 through the suspension rope 402. The tension sensor 403 will be affected by the traction force of the suspension rope 402 and the tension of the second clamping component 3, so that the tension sensor 403 will generate electrical signals of different values. The tension sensor 403 will transmit the electrical signal to the PLC, so that the value of the tension that the fabric can withstand can be known.

[0028] Preferably, the clamping frame 204 of the second clamping assembly 3 is slidably connected to the slide groove 401, and the first clamping assembly 203 and the second clamping assembly 3 are symmetrically arranged.

[0029] When the servo motor 404 drives the winding roller 405 to rotate, the suspension rope 402 is wound around the winding roller 405 , thereby driving the second clamping assembly 3 to slide inside the slide groove 401 to complete the tension detection of the fabric.

[0030] Preferably, a symmetrical limiting plate 5 is provided between the second clamping assembly 3 and the servo motor 404 , and the limiting plate 5 is fixedly connected to the fixing frame 4 .

[0031] Among them, the set limit plate 5 plays a protective role on the second clamping component 3 and the servo motor 404, preventing the second clamping component 3 from colliding with the servo motor 404 under the action of inertia due to fabric breakage when the second clamping component 3 is detecting the fabric, thereby protecting the components.

[0032] Preferably, adjacent sides of the symmetrical limiting plates 5 are rotatably connected with rollers 501 , and the rollers 501 are connected to the suspension ropes 402 .

[0033] When the suspension rope 402 moves inside the limiting plate 5, the roller 501 can reduce the friction between the suspension rope 402 and the limiting plate 5, thereby avoiding detection errors.

[0034] Working principle: by placing the two ends of the fabric respectively inside the first clamping component 203 and the second clamping component 3, and then rotating the spiral rod 206 to move the clamping plate 205 inside the clamping frame 204, the fabric is clamped inside the groove 209 through the protrusion 207, and the ejector pin 208 passes through the gap of the fabric and is inserted into the needle hole 210, thereby fixing the position of the fabric inside the first clamping component 203 and the second clamping component 3, so that when the second clamping component 3 is pulled by the suspension rope 402, the fabric will not fall off from the first clamping component 203 and the second clamping component 3, thereby facilitating the tension detection of the fabric.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
